3 Claims. (Cl. 15-257) This invention relates to wax polishing, buflingor abrading of lacquered surfaces, glazed or plated steel commonly usedin automobiles, steel furniture, steel oflice equipment, steel walls andappliances such as refrigerators, stoves, washers or driers and thelike, and of materials responsive to magnetic influences.

An object of my invention is to reduce the muscular force and effortrequired in the polishing, bufling or abrading of surfaces constructedof magnetizable materials or the like.

A further object of the invention is to permit the effective polishingof curved or irregular surfaces of magnetic material.

A feature of the invention is a polisher or the like containing magnetsembedded in a flexible or articulated casing of non-magnetic material.

Another feature of the invention is a polisher or the like comprisingflexible sections having magnets encased therein, whereby the attractivemagnetic force holds the polisher firmly to a magnetizab-le surface andyet the polisher can easily be slid along the surface as it polishes.

' Another feature of the invention is an articulated pols Patent isher,having flexible casings for the magnets which are so tapered as toprovide an effective hand grip for the operator.

'-In accordance with my invention, one or more magnets of such alloys ascobalt, nickel, steel or any combination thereof, also known as alnicoor any other suitable magnetic material that will exert, and retainindefinitely, an attractive force of at least 16 ounces to 32 ounces ormore per square inch of area, are encased within a durable envelope ofrubber, plastic, wood, leather or cloth or any other non-magneticsuitable material or any combination thereof. The casing is articulatedor arranged in segmented sections to provide for flexibility in one orseveral directions to allow it to follow contours of curved surfaces.The upper part of the casing with the included magnets forms aneffective hand grip. One or several layers of a suitable material, suchas cheesecloth are folded over the entire casing, and by gripping itfirmly and rubbing lightly over the previously applied wax, buflingpowder or abrading material applied to the magnetic surface, an easy andeffective polishing may be accomplished. While it is necessary to exertfrom five to ten pounds of force to lift the device vertically from thesurface, it is quite easy to slide it along the plane of the object tobe polished without relaxing or diminishing the attraction of themagnets. By means of the magnetic forces involved, it is no longernecessary to press down hard against the metal surface since the magnetssupply suflicient downward pressure to cause the wax to be well rubbedin, or to cause the buifing or abrading materials to remove desiredsurface layers of paint or dirt. Another important advantage of thisconstruction is that the polisher device need not be laid aside whenapplying wax, polishing or abrading materials, but may be convenientlyleft adhering to the workice ing area, even on vertical members such asdoors or sides of fenders and bodies within convenient reach.

For further comprehension of my invention and of the objects andadvantages thereof, reference will be had to the following descriptionsand drawings and to the appended claims in which the several novelfeatures are more particularly set forth and enumerated.

In the accompanying drawing,

Figs. 1 and 2 are perspective views of the magnetic polishing device inaccordance with this invention, with Fig. 1 showing it applied to anautomobile,

Fig. 3 is a cross sectional view of Fig. 2 along a line 3-3 and showingthe disposition of the magnets enclosed in the flexible casing,

Fig. 4 is a view taken along line 44 of Fig. 3,

Fig. 5 is a sectional view taken along line 5-5 of Fig. 3.

Referring to Fig. 1 of the drawing, the magneticpolisher device 15 ofthe invention is shown with a cheesecloth or chamois cloth 10 or thelike wrapped around it for polishing a steel, iron magnetic material,such as the automobile body 5 and the like.

The magnetic polisher device 15, as-illustrated in Figs. 2, 3, 4, 5consists of one or more magnets 12 of alnico or the like, each moldedinto a flexible rubber or plastic casing 11 to form articulated sectionsjoined by an integral common flat base 13. Each section 11 is taperedupwardly from the flat base 13 and spaced from its neighboring sectionby a V-shaped depression to provide an effective flexible hand grip forthe operator.

To polish enameled or lacquered steel surfaces, wax is first appliedthereto by the operator. Several layers of cheesecloth 10 are thenwrapped around the polisher device 15 as in Fig. l and over its bottomflat surface 13. The operator grips the polisher device by its upperflexible portion and in the customary manner rubs the wax to provide apolished surface. It is necessary only to move the polisher device 15 ina sidewise or rotary motion as the encased magnets 12 exert sufficientdownward pressure on a steel surface to permit the Wax to be rubbed oneffectively. It has been found that the magnetic polisher device 15reduces considerably the muscular effort heretofore found necessary toobtain a high gloss finish. The device is likewise adapted forcompounding with painters compound prior to polishing, or abradingsurfaces with abrasive powders in a manner similar to that heretoforedescribed.

The articulated sections 11 or a corresponding arrangement of segmentedsections is capable of providing flexibility in one or severaldirections, whereby the magnetic polisher device 15 may follow easilythe contours of curved or irregular steel surfaces, as for example,fenders of automobiles. The segmented sections may, if desired, be flatsquares on top and bottom.

It should be understood that the polisher device disclosed may be usedby means of a special holder in stationary or portable power drivenequipment, which may oscillate or rotate the device over steel or othermagnetic surfaces to be polished, buffed or abraded.

Further, the permanent magnets may be replaced by electromagnets whichfurnish the attracting force except that this species of device would belimited to areas where electric power is available, and by the length ofthe supply cord.

While I have described and illustrated the present and preferredembodiment of my invention, it is to be understood that -I do not limitmyself to the exact construction herein described and disclosed, andreserve the right to make any changes and modifications regarding thesize, strength, composition and number of magnetic materials as well assize, shape or composition of the encapsulating materials or any othersuch alterations that are within the scope of'this invention.

Having thus described my invention, what I claim as new and desire tosecure by United States Letters Patent is:

1. A magnetic polisher device for waxing a magnetiz able. surfacecomprising a unitary molded, rubber casing having tapered segmentsspaced apart at their upper ends tov constitute a flexible hand grip,magnets imbedded in segments, and a flat non-magnetic, articulated baseon said casing and joining said segments to act as a backing for apolishing cloth of like area, and to be slid easily over said surfaceWithout altering the magnetic force appreciably, the magnetic force ofsaid magnets being in the range of 1-2 pounds per square inch of flatbase.

2. A magnetic polisher device for waxing magnetic surfaces comprising aunitary, molded casing of nonmagnetic, rubbery material formed intosegments, trapezoidal in cross-section, a magnet embedded in each segment, and a flat non-magnetic articulated base integral with saidsegments for sliding over the magnetic surface wherein the magneticforce exerted by said magnets is in the range of 1-2 pounds per squareinch to hold the casing to said surface transversely and permit the flatbase to he slid laterally.
